How to put two variables into one ggplot

Dataset: data

Region Forest Lakes
North 30 40
West 40 100
South 12 30
Central 44 200 
data %>%
  ggplot(aes(x = Region, y = Forest)) +
  geom_col() +
  facet_wrap(~Lakes)  + ggtitle("Lakes and Forest in different Regions")

Unfortunately this is not the right thing.

I would like to show for each region how much lakes and forests they have and then the nearest region in x-axis. How does it work?

Reshape to 'long' format with pivot_longer and then use geom_col with position='dodge'

library(dplyr)
library(tidyr)
library(ggplot2)
data %>% 
  pivot_longer(cols = Forest:Lakes) %>%
  ggplot(aes(x = Region, y = value, fill = name)) + 
  geom_col(position = 'dodge')  + 
  ggtitle("Lakes and Forest in different Regions")
